This circuit number LM386 IC is used as the IC, which is popular is that it has. It is a simple circuit. Less equipment items. Suitable for use or used in small trials. The properties of the IC can be used from 4V-12V power supply for low current at 50 mA only. And the frequency [...]
This circuit be signal sound expansion from condenser microphone give with small-sized loudspeaker. It compose the importance is part pre mic use transistor just one enlarge sound signal gives the power goes up change come to a part amplifier with the integrated circuit LM386 utter go out give a loudspeaker. When feed power supply 9V [...]
This simple amplifier shows the LM386 in a high-gain configuration (A = 200). For a maximum gain of only 20, leave out the 10 uF connected from pin 1 to pin 8. Maximum gains between 20 and 200 may be realized by adding a selected resistor in series with the same 10 uF capacitor. The [...]
